A man used a piece of broke mug as a weapon to attack his partner during a row, a court has heard.
After slashing the woman to the neck he tried to stop her calling the police then followed her out into the street and attacked her again.
Sending Daniel Anthony Davies to prison, a judge told the 35-year-old old he posed a "real risk to any woman unlucky enough to be in a relationship with you".
Swansea Crown Court heard the incident was the culmination of arguments between couple in the days after Christmas 2020.
Jim Davis, prosecuting, said on the morning of December 28 another row broke out during which Davies threw a mug which smashed on impact. The defendant then picked up a shard of the broken mug and used it to cut the woman to the left side of the neck, causing a wound which "bled profusely".
The court heard the woman reached for the phone to call 999 and there was a struggle between them as Davies tried to prevent her getting help. The woman then fled the Swansea property and defendant followed her into the street, pushing her into a wall.
Police were soon on the scene and arrested Davies and his partner was taken to Morriston Hospital where the wound was closed with stitches.

Davies, of David Williams Terrace, Port Tennant, Swansea, admitted assault occasioning actual bodily harm. The court heard he has previous convictions for domestic assaults as well as for harassment and breaching restraining orders.
John Tarrant, for Davies, said the relationship between the defendant and his partner had been a "toxic" one and his client had mental health issues and learning difficulties.
Judge Paul Thomas QC said Davies' behaviour towards partners was concerning. He told the defendant that it was clear from his record, from the contents of a pre-sentence report, and from the facts of the case that he was "a man who represents a real risk to any woman unlucky enough to be in a relationship with you".
The judge said that while it was accepted the defendant had mental health issues the pre-sentence report noted that he was considered to be a "manipulative" person.
Giving the defendant a one-quarter discount for his guilty plea the judge sentenced him to 36 weeks in prison. Davies will serve up to half that period in custody before being released on licence to serve the remainder in the community.
The defendant was made the subject of a restraining order banning him from contacting his victim for the next three years.
